SPECIFICATION forming part of Letters Patent No 335,972, dated February 9, 1886.

Application filed May 5, 1985. Serial No. 164,511. (No model.)

i that class of typewriters in which the types are attached to levers or arms which are actuated by key-levers.

The object of this invention is to improve the mechanism whereby the types are guided to the point of impression; also, to improve the spacing mechanism, and, finally, to iinprove the construction of the papercarriage and the devices whereby said carriage is actuated.

My invention consists, to these ends, of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting` of three sheets, Figure l is a longitudinal sectional elevation of my improved type-writing machina Fig. 2is a horizontal section of the same in line a: Fig. l. Fig. 3 is a cross-section of the paper-carriage in line y y, Fig. l. Fig. et is an elevation of the guides of the typelevers. Fig. 5 is a cross-section in line w w, Fig. l. Fig. 6 is aside elevation of the feed-carriage. Fig. 7 is a top plan View of the papercarriage. Figs. 8, 9, l0, and l1 are detached perspective views illustrating the construction of the type-levers. Fig. 12 is a perspective view of a modified construction of the type-levers. Fig. 13 is a front elevation showing a modified construction of the guides of the type-levers. Fig. 14 is a cross-section in line z z, Fig. 1.

Like letters of reference refer to like parts in the several figures.

A A represent the side pieces of the frame,

. and A the top frame, resting on the same and of the kcylevers and are secured to a crosspiece, d.

d2 represents tensionscrews arranged side b v side in threaded openings in the cross-piece d and bearing against the under side of the springs d, whereby the tension of the latter may be regulated. rPhe upper side of thekeylevers G abut against the under side of a crossbar, C', secured to the side pieces, A A, where-1 by the upward movement of the levers C is arrested.

C2 represents the keys of the levers C, which are secured thereto by soldering or otherwise. The key-levers C are preferably constructed of thin sheet metal-such as brass, tin, &c.-- bent to form a bar or lapped, as shown in Figs. 8, 9, and 10, or bent and soldered to form a tube, as represented in Fig. ll, whereby a light and strong bar is formed.

D represents the typebars, forming practically a continuation of the key-levers C, and

`D are the type secured to the rear ends of the same. The type-bars D are pivoted or hinged at e to the rear endsl of the key-levers C by vertical pivots, so that each type-bar can swing in a horizontal plane on the hinge orjoint by which it is attached to its key-lever. This hinge is preferably composed, as represented in Fig. 1, of a bifurcated frame, e', which is secured in a socket formed in the inner end of the key-lever, and which frame receives the v central guide inclined, so that each guide will direct its key-bar toward the point at which the impression is delivered. Each guide E outside of the central guide is composed of a main inclined portion, f, and an upper and Vlower vertical portion, ffz, so that upon depressing a keylever C its typebar D is caused to rst move vertically sufficiently to IOO 25 the type-bar, as represented in Fig. 12.

permit its free or-rear end to pass over the next adjacent type and clear the same before the type-bar turns on its pi'vot e and begins its ascent on the inclined portion fof its guide.

By this upward movement the type-bar D is swung on its hinge e until it has reached the end of the incline of its guide and the type presents its face to a guide or throat piece, f3, secured centrally in the top frame, A, below 1o the point of impression, when a further depression of the key-lever moves the type-bar through the uppervertical portion of its guide until its type enters the throat f3. strikes the paper, and delivers the impression. The

throat f 3 insures the'proper centering of each type when it enters the same before it delivers the impression upon the paper.

It is obvious that the center key-lever and type-bar can be rigidly connected, because their movement takes place in a vertical plane.

Alt is obvious that a iiexible or spring bar, f4, may be substituted for the hinged joint, for the purpose of connecting the key-lever with In this construction the flexible portion f4 would practically perform the same function as if the parts were jointed and the same result obtained.

lf desired, the type-bars may be guided toward the impression-point, as shown in Fig. 13, byinclines F, arranged on either side of the center of the machine, instead of an individual guide for each type-bar, as above described, whereby the same result would be obtained. The guide-bars F are secured at their upper ends to the throat f3 of the top frame, A, and at their lower ends to posts 40 F represents line wire springs, which are secured between the type-bars D to a crosspiece,f6, connecting the side frames, A A. The springs F simply serve to Areturn the type-bars D to their proper places after having been operated upon. l

G represents a U-shaped spacing-frame arranged underneath the key-levers C, and which is secured to a rock-shaft, g, journaled in suitable bearings, g, in the side pieces, A A.

`G .represents the' spacebar connecting the ends of the frame G, and which is held with its upper surface against the under side of the key-levers C by springs g". G2 represents the space-key secured to the bar G by vertical standards G3.

' `g3 are adjustable stops, which limit the downward movement of the bar G, and which are secured to the side pieces, A A.

,gfrepresents a spring-pawl secured to the 6b rear vcurved portion of the frame G, so as to move therewith, and engaging with its upper end with a ratchet-wheel, H, which latter is secured on a short shaft, la, journaled in bearings h, formed on the underside of the top frame, A. Y

h2 h3 are notches or depressions formed in the upper side of the space-bar G. The notches h? .h5 are made of different depths and arranged underneath the different key-levers in such manner that the levers of the types which require but a single space movement of the carriage-such as i t Z, Src-stand above the deepest notches It, while the key-levers of the types requiring a double space movement ofthe carriage-such-as N U D, Src-stand above the shallow notches l1, and the key-levers of the types requiring a triple movement of the carriage-such as MNV, Sta-rest on the upper side ofthe space bar G. It is obvious that the same effect would be produced by making the upper surface of the space-bar G straight and arranging the key-levers at greater or less distances above the same, so that the key-levers requiring a triple space movement rest directly upon the space-bar and move the latter at once upon being depressed, while the keylevers requiring a double or single space movement stand at varying distances above the space-bar and have a proper amount of dead movement before moving the-space-bar. Upon depressing a key-lever requiring a triple space movement of the carriage the space-bar G immediately takes part in such downward movement and causes the pawl g4 to ride over a suflicient number of teeth on the ratchetwheel H to eii'ect the required lateral movement of the carriage B, when the space-frame G is returned to its former position by the springs g2. The notches h2 h3 permit the keylevers C, arranged above the same, to travel downward a certain distance before they come in contact with the space-bar G, whereby the pawl g4 of the frame G is lifted sufficiently-to engage over the number of teeth on the wheel H to effect a single or double space movement of the carriage to correspond with the character of the key-lever which has been depressed. By this construction the spacing between the various printed characters is varied in accordance with the space required for the same, whereby the printed matter is caused to assume a neater and more uniform appearance than when the spaces between the various widths of characters are equal.

I representsa horizontal guide-bar arranged in standards z' in the top frame, A. The carriage B is supported and guided at its rear end by collars or sleeves yi, moving on the rod I, and at its front end by a central roller or wheel, if, traversing a track or way, i, on the frame A.

I represents a rack-bar arranged between the vertical side frames of the carriage B, and which is capable of slight vertical movement in guides or ways if, formed on the carriage B. The rack-bar l engages with its lower toothed portion with a screw-wheel, J, which is secured to the shaft la, so as to turn therewith.

j represents a horizontal rock-shaft mounted in bearingsjon the carriage B, and which is provided at one end with a handle or thumbpiece, ji, whereby the rock-shaft can be turned.

73 represents two short ngers or arms secured to the shaft j, and which engage with IOO IIO

Athe pad to the types.

their free ends in openings or slots j, formed in ears j on the upper portion of the rackbar l.

K represents spiral springs surrounding the shaft j, and which are secured to the frame B and bear with their free ends upon the arms j, whereby the rack-bar l is held down upon the frameB and in engagement with thescrewwheel J.

j K represents projections or noses on the bar I', which rest upon the frame B and limit the downward movement of the rack-bar I. By turning the thumb-piece j2 in the proper direction 'the lingers j will lift the rack-bar I out of engagement with the screw-wheel J, whereby the carriageis disengaged from the screw-Wheel and free to be moved in either direction. Upon releasing the thumb-piece j'l the springs K return the rack I/ to its former position, and cause it to again engage with the wheel J. The carriage B is moved in the proper direction by turning the screwwheel J by means of the ratchet-wheel H, and pawl g4, and space-frame G, as above described.

k represents a detent-pawl, arranged underneath the top frame, A', and engaging with the ratchet-wheel H.

K2 represents an inclined toothed bar secured to the top frame, A.

k represents a segmental tooth formed on the under side of one or both collars Z of the carriage B, and arranged with its front end immediately in rear of the bar K2, as represented in Fig. l. The tooth lc engages between the teeth of the bar K when the carriage B is lifted or turned upon the rod I, thereby preventing the carriage B from moving on the rod I and insuring a return of the carriage to its former position when the carriage is lowered.

L represents the platen arranged on the frame B of the carriage above the throat f3, and composed of a metallic frame or plate, Z, which is provided on its under side with an impression-pad, Z', of rubber or other suitable material, which is detachably secured to the frame Z, so that it can be renewed when worn out. The frame Z is provided at both ends with ears Z2, which are pivoted at Za to a supporting-frame, M. The ears Z2 are provided with segmental slots m, through which passv screws m', whereby the platen is secured in position in the supporting-frame M. Upon releasing the screws m the platen can be turned on its pivots to present a different portion of The supporting-frame M is hinged at one end to the carriage-frame B, as shown at n, Fig. 7, and provided at its opposite end with a thumb-piece, n', whereby it can be lifted or turned on its pivots.

O O represent the feed-rollers journaled in beari'ngs in the carriage-frame B,'and O2 O3 are similar rollers, resting on the rollers O O and journaled in bearings in the supportingframe M'of the platen. Y v

P represents a ratchet-wheel secured to one end of the shaft m2 of the front feed-roller, O.

P' represents an elbow-lever pivoted on the shaft m, and having its lower arm, P, extending rearward on one side of the carriage-frame, and which is provided with a pawl, p, engaging with the ratchet-wheel P, while its upper arm, P3, extends upward beyond the carriageframe.

v p2 is a detent-pawl pivoted to the carriageframe B, and engaging with the ratchet- Wheel P.

p4 represents a nose formed on the curved rear end of the lower arm, P, which supports the latter on a pin, p5, secured to the carriageframe. required distance and it is desired to return the same to feed the paper forward, the lever P is turned in the direction indicated by the arrow in Fig. 6, thereby turning the rollerO by the pawl p engaging with the ratchet-wheel P, and feeding the sheet of paper by means of the rollers O O. When this movement of the lever P takes place,the rear curved end of the arm l?2 comes in contact with the under side of the forward arm of the thumb-piece j2 of the shaft j, and turns thelatter, whereby the rackbar I is lifted out of engagement with the screw-wheel J and is free to be brought back. In this manner the paper-carriage is released from its actuating mechanism by the same movement of the elbow-lever P whereby the paper is fed forward, so that` the paper-carriage is free to be moved back on the supporting-bar I.

Q is an adjustable stop secured in an elongated opening inthe carriage-frame B, whereby the throw of the elbow-lever P is regulated, thereby regulating the distance between the lines.
